Y-shaped triangular steel truss beam bridge

Abstract

The invention discloses a Y-shaped triangular steel truss beam bridge suitable for span less than 200 m. The Y-shaped triangular steel truss bridge comprises a first truss and two second trusses, one end of the first truss and the second trusses are intersected at one point to form a bridge main beam, the intersected point of the first truss and the second trusses is at the highest position of truss height of the bridge main beam, the bridge main beam is integrally a tripod spatially, a plane of the bridge main beam is Y-shaped, and the second trusses are spliced to form a V-shaped main truss branched portion in the Y-shaped bridge main beam. The bridge is integrally in the shape of a tripod, the planar shape is a Y-shaped branch, and a fade shape is a triangular steel truss beam remodel. On the premise that large span is guaranteed, space below a bridge floor is small in thickness, integral rigidity is high, and the bridge is high in windproofness and seismic resistance and novel and attractive in shape and can serve as a city landmark building.

Description

technical field [0001] The invention relates to a half-piercing steel truss bridge in the field of bridge type scheme design, in particular to a triangular steel truss bridge suitable for Y-shaped split limbs with a span of less than 200m. Background technique [0002] Traditional steel truss bridges are widely used in highway and railway bridge construction, and are bridge structures with very strong spanning capacity. For more than half a century, a large number of steel truss bridges have been built in my country, and this type of bridge occupies an important position in the bridge steel structure. Under the premise of today's urban bridge construction, the aesthetic feeling of the building is obviously very important; the long-span truss girder bridge is often difficult to meet the requirements for the shape of the bridge because its structural form is too classic and single. At the same time, for specific construction conditions such as T-shaped intersections in cities...

Problems solved by technology

At the same time, for specific construction conditions such as T-shaped intersections in cities, roads on the island, and limited land acquisition and demolition, conventional steel truss bridges are difficult to apply to these situations, and bifurcated special-shaped structures are often required
